A field experiment was carried out at Regional Sericultural Research Station, Kodathi, Bangalore during 2014-16 to evaluate the impact of vermicomposts generated through the use of various resource materials such as silkworm rearing residue (SRR), seri-farm residue (SFR), avenue tree debris (ATD) and municipal corporation waste (MCW) in combination with recommended dose of NPK and FYM in mulberry. A total of 10 mulberry leaf harvests data revealed that 5mt/ha/yr vermicompost of SRR in combination with 50% reduced dose of FYM (10mt/ha/yr) along with NPK (@350:140:140kg/ha/yr) yielded increased leaf (T3-10,877.9kg/ha/cr) followed by the vermicompost of MCW (T5-10,345.2kg/ha/cr), vermicompost of ATD (T4-9,657.9) and SFR (T2-9,638.6), respectively compared with the control (T1-8,969.7kg/ha/cr) where recommended N350P140K140+20MT FYM/ha/yr incorporated. Similar trend was noticed in case of plant growth and leaf yield parameters. Chemo assay of mulberry leaves viz. leaf moisture, total chlorophylls and leaf protein further supported the above results recording improved levels in the above treatments compared to control. Encouraging results were also noticed in case of soil nutrient status after experimentation in the vermicompost imparted plots compared to the control plots indicating that vermicompost combination under 50% reduced level of FYM and recommended NPK has an ability of improving sustainable mulberry crop production thereby appropriate utilization of various non-renewable wastes in to renewable nutrient rich composts minimizing the ever-growing landfills, preventing environmental pollution and helping appropriate utilization for the serifarming enrichment. From the results it is imperative that popularization of vermicomposting technologies for the appropriate management of all the resourceful wastes for suitable utilization in their farming not only contributes in appropriate utilization of these non-renewable wastes but also promotes environmental free farming.
